Abstract

Compound 5, a cinnamanilide derivative, upregulates brain derivated neurotrophic factor (BDNF) expression but with low soluablity. In this study, PX5–9, a N-oxide derivative of 5, demonstrated significant protective effects in the HT22 glutamate-induced toxicity model and showed no significant toxicity at 30 μM. Western blot analysis confirmed that PX5–9 increased BDNF levels similar to 5. Solubility tests revealed a significant improvement in PX5–9 (37.10 ± 0.33 μg/mL) compared to 5 (< 15 ng/mL). Pharmacokinetic studies of PX5–9 revealed favorable properties, fast absorption and also can be transformated into parent compound 5, suggesting it is a potential candidate for these diseases involving with BDNF. The N-oxide modification might be a good prodrug design to enhance solubility while preserving biological activity.

n -氧化物肉桂苯胺衍生物PX5-9的设计和表征：改善溶解度和上调BDNF

化合物5，肉桂苯胺衍生物，上调脑衍生神经营养因子（BDNF）的表达，但具有低溶解性。在本研究中，5的n -氧化物衍生物PX5-9在HT22谷氨酸诱导的毒性模型中显示出明显的保护作用，在30 μM下无明显毒性。Western blot分析证实PX5-9增加BDNF水平与5相似。溶解度测试显示PX5-9与5 (<；15 ng / mL)。PX5-9的药代动力学研究显示其具有良好的特性，吸收快，并且可以转化为母体化合物5，提示其是BDNF相关疾病的潜在候选者。n -氧化物修饰可能是一个很好的前药设计，以提高溶解度，同时保持生物活性。
